We know, we know. The title of this blog post makes it seems like gas furnaces are inherently dangerous. This is simply not true. What is true, however, is that if you don’t properly care for your gas furnace, it can become dangerous. Why is this? Well because gas lines can leak, and when a furnace isn’t well-maintained or if the damage isn’t repaired, it’s more likely for this to occur.
The biggest risk is a carbon monoxide (CO) leak. CO exposure is one of the leading causes of household illnesses and injury, and even leads to many fatalities each year. We say this not to scare you, but for you to be aware. The component that you need to be most worried about is the heat exchanger. Read on as we uncover more about the heat exchanger, as well as our #1 safety tip if you have a gas furnace–scheduling annual furnace maintenance.
